Abstract
A decrease in cost is devised at an exhaust treatment device that purifies exhaust from an internal engine by a catalyst that is heated from a catalyst support that generates heat by being energized, and that returns some of exhaust that has been purified to the internal combustion engine. A cooling member is provided at a portion of an exhaust pipe that is between an engine and an upstream catalytic converter, and a circulation pipe is branched-off from between the upstream catalytic converter and a vibration cut-off member that is at a downstream side.
